Showtime has released this new featurette on "Penny Dreadful," starring Josh Hartnett, Timothy Dalton, Eva Green, Reeve Carney, Rory Kinnear, Billie Piper, Danny Sapani and Harry Treadaway. The show will premiere on May 11.

In "Penny Dreadful," some of literature's most famously terrifying characters – including Dr. Frankenstein, Dorian Gray and iconic figures from the novel Dracula – have become embroiled in Victorian London. The series is a frightening psychosexual thriller created, written and executive produced by three-time Oscar nominee John Logan (Hugo, The Aviator, Gladiator) and executive produced by Logan's Desert Wolf Productions, along with Oscar winner Sam Mendes (American Beauty, Skyfall) and Pippa Harris (Revolutionary Road), both of Neal Street.
